摘要

我们展示了一种高性能的InGaAs-on-silicon APD，具有极低的暗电流密度(0.7 mA/cm/sup 2/)，高雪崩增益(M/spl Gt/100)， rc限制带宽为1.45 GHz，增益带宽积为290 GHz。我们估计，与最先进的基于inp的APD接收器相比，我们的设备可以实现5 dB的灵敏度提高。我们目前正在测量APD的过量噪声系数。我们将在会议上报告这个测量结果。

High-performance InGaAs-on-silicon avalanche photodiodes

We have demonstrated a high-performance InGaAs-on-silicon APD that exhibits a very low dark current density of 0.7 mA/cm/sup 2/, high avalanche gain (M/spl Gt/100), an RC-limited bandwidth of 1.45 GHz, and a gain-bandwidth product of 290 GHz. We estimate that our device can achieve a sensitivity improvement of 5 dB compared to state-of-the-art InP-based APD receivers. We are currently measuring the APD excess noise factor. We will report this measurement at the conference.
